I was able to come up with something. You didn't specify what kind of robot, or what actions he'll be doing, or how many frames of animation, or the point of view, or whether it was a 3D model or 2D sprite, or any other details about the character like poly count, sprite size, etc... so I took a few liberties and came up with a one frame, arbitrarily sized, 2D side-view robot eating a sandwich.

He doesn't have any weapons, since he's a sandwich-eating robot from the planet Quiznos IV who is on a quest to eat everything after his family was struck down by food poisoning after eating some raunchy sun-dried tomatoes.

If you decide to use this robot all I ask are royalties of 10% gross sales. For that price I can provide different poses of the robot, such as the robot eating a cheese sandwich, or the robot eating a honey bacon sandwich with extra onions and light on the mayo.

Or, if you decide not to use this robot and wish to create a character yourself, you can check out some of these links:

There is no "duh" about that; this is the first time you've mentioned 3D. It's scarcely a given.

There's no reason to be rude, either. Being rude when asking for help is not likely to work in your favor.

Even if you had been clear and polite from the beginning, it's unlikely that someone is just going to give you a custom-made 3D model. You can get a bunch of free Quake 2 and 3 models from http://polycount.com/ , some of which are very good. I suggest starting there. Once you've got something to show for your efforts, someone might put some dedicated effort into helping you.
